TECHNICAL FIELD

The present invention relates to a compound capable of binding sphingosine-1-phosphate receptor which is useful as a medicament and a medicament containing the same as an active ingredient.

In particular, the present invention relates to:

(1) a compound represented by formula (I):

wherein, all symbols have the same meanings as described below;

a salt thereof, an N-oxide form thereof, a solvate thereof, or a prodrug thereof; and

(2) a medicament containing the compound represented by formula (I), a salt thereof, an N-oxide form thereof, a solvate thereof, or a prodrug thereof as an active ingredient.

BACKGROUND ART

Sphingosine-1-phosphate (hereinafter, abbreviated as “SIP”) represented by formula (A) is a lipid that is synthesized by the intracellular metabolic turnover of sphingolipids or the extracellular action of secretory sphingosine kinase. It is pointed out that S1P acts as an intercellular and intracellular messenger (Biochem. Pharm., 58, 201 (1999)).

As receptors of S1P, EDG-1 which is a G-protein coupled receptor and its analogous molecules, EDG-3, EDG-5, EDG-6 and EDG-8 (also called S1P₁, S1P₃, S1P₂, S1P₄, and S1P₅, respectively) are known. They are called EDG family together with EDG-2, EDG-4 and EDG-7 which are receptors of lysophosphatidic acid (LPA). S1P receptors binds to S1P and deliver signals into cells via G-protein coupled with the receptors. Gs, Gi, Gq and G_(12/13) etc. are known as G-proteins to which S1P receptor can couple, and it is considered that the receptor is involved in responses such as increase of cell proliferation, suppression of cell proliferation, induction of cell chemotaxis, and inhibition of cell chemotaxis.

As biological action of S1P, inhibition of migration of smooth muscle cells or cancer cells, platelet aggregation, induction of cell chemotaxis, inhibition of cell chemotaxis and the like are known in vitro experiments, and as the results of in vivo experiments, it is known that S1P shows effects of controlling blood pressure, promoting angiogenesis, reducing renal blood flow, inhibiting lung fibrosis, promoting the lymphocyte homing into lymphatic organs, and the like. It is considered that those various physiological effects are mediated by S1P receptors existing in cell membrane. However, it has been scarcely clarified excluding some cases which subtypes of S1P receptors mediate these effects in practice.

Recently, from the study for EDG-1 knock-out mice, it is strongly indicated that S1P induced angiogenesis via EDG-1 (J. Clin. Invest., 106, 951 (2000)). Therefore, it is suggested that an EDG-1 agonist is used as an agent for treating diseases caused by anangioplasia. For example, it is used as an agent for prevention and/or treatment of peripheral arterial disease such as arteriosclerosis obliterans, thromboangiitis obliterans, Buerger's disease, or diabetic neuropathy; varicose vein such as hemorrhoid, anal fissure, or anal fistula; dissecting aneurysm of the aorta, sepsis, inflammatory disease such as angiitis, nephritis, or pneumonia, various edematous disease involved in ischemia of various organ and increase of the blood permeability, for example, cerebral infarction, myocardial infarction, angina, congestive heart failure, pleuritis, DIC (disseminated intravascular coagulation), or multiple organ failure. In addition, angioplasty is closely related to osteogenesis, so the EDG-1 agonist can also be used as a treating agent for abnormal bone metabolism such as osteoporosis. In addition, from the study for the knock-out mice, it is also indicated that there is a possibility that EDG-1 inhibited migration of a vascular smooth muscle. Therefore, the EDG-1 agonist can also be used as an agent for prevention and/or treatment of arteriosclerosis. In addition, the EDG-1 agonist can also be used as an agent for enhancing wound healing of cornea, skin, digestive organs, or the like, or, for example, as an agent for prevention and/or treatment of bedsore, burn, ulcerative colitis, Crohn's disease, or the like. Further, the EDG-1 agonist can also be used as a preoperative, postoperative, and/or prognostic activator for blood vessel accompanying transplantation of various organs, for example, as an adhesion activator of transplanted organs such as heart transplantation, renal transplantation, dermal transplantation or liver transplantation.

In addition, the S1P is known to be effective to mouse bleomycin-elicited pulmonary fibrosis (see, WO 01/03739). Therefore, the S1P agonist can be used as an agent for prevention and/or treatment of diseases caused by fibrosis of various organs, for example, fibrosis including pulmonary fibrosis, liver fibrosis, and the like, interstitial pneumonitis, chronic pepatitis, liver cirrhosis, chronic renal insufficiency, and renal glomerular sclerosis.

In addition, it was reported that the S1P acts to promote secretion of insulin from a pancriatic β cell via EDG-3, and that the S1P inhibits glucagon-dependent insulin secretion via EDG-1 (see, for example, Endocrine Journal, 47(3), 261, (2000) and Diabetes, 52, 1986, (2003)). Thus, an EDG-1 agonist may be used as an agent for prevention and/or treatment of diabetes, in particular, as a glucose metabolism-improving agent, an insulin secretion-promoting agent, or a pancriatic cell-protecting agent.

On the other hand, EDG-6 is localized and strongly expressed in cells and organs of the lymphatic and hematopoietic systems including spleen, leukocytes, lymph gland, thymus, bone marrow, lung and the like, which suggests the possibility that the EDG-6 is closely related to the effects of S1P in the course of inflammation or in the immune system (Biochem. Biophys. Res. Commun., 268, 583 (2000)).

Moreover, it is known that the EDG-6 polypeptide or its homologue is involved in immunomodulation, antiinflammation and the like in a similar manner as EDG-1, which brings about the potential usability of those substances in treating autoimmune diseases (e.g., systemic lupus erythematosus, rheumatoid arthritis, myasthenia gravis and the like), allergic diseases (e.g., atopic dermatitis and the like), asthma, inflammatory diseases, infection, ulcer, lymphoma, malignant tumor (e.g., cancer and the like), leukemia, arteriosclerosis, multiple organ failure, diseases associated with lymphocyte infiltration into a tissue (e.g., reperfusion injury after ischemia, and the like), and the like.

From these findings, a drug which acts on EDG-1 and/or EDG-6 is thought to be useful as an agent for prevention and/or treatment of: a peripheral arterial disease such as arteriosclerosis obliterans, thromboangiitis obliterans, Buerger's disease, or diabetic neuropathy; varicose vein such as hemorrhoid, anal fissure, or anal fistula; dissecting aneurysm of the aorta; sepsis; an inflammatory disease such as angiitis, nephritis, or pneumonia; various edematous disease involved in ischemia of various organs and increase of the blood permeability, for example, cerebral stroke, ischemia-reperfusion injury, cerebral infarction, myocardial infarction, angina, congestive heart failure, pleuritis, DIC, or multiple organ failure; bedsore; burn; trauma injury; inflammatory bowel disease; genetic disease; osteoporosis; arteriosclerosis; fibrosis including pulmonary fibrosis, liver fibrosis, and the like; interstitial pneumotitis; chronic hepatitis; liver cirrhosis; chronic renal insufficiency; renal glomerular sclerosis; diabetes; rejection in transplantation; rejection of a transplanted organ; graft versus host disease; an autoimmune disease (e.g., systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis, psoriasis, ulcerative colitis, Crohn's disease, myasthenia gravis, autoimmune diabetes, and the like); an allergic disease (e.g., atopic dermatitis, pollen disease, food allergy, and the like); asthma; infectious disease; ulcer; lymphoma; malignant tumor (e.g., cancer and the like); leukemia; a disease associated with lymphocyte infiltration into a tissue; and the like. In addition, those drugs are thought to be useful as a preoperative, postoperative, and/or prognostic activator for blood vessel accompanying transplantation of various organs, tissues, and/or cells, for example, as an adhesion activator of transplanted organs such as heart transplantation, renal transplantation, dermal transplantation or liver transplantation.

Recently, it was reported that an EDG-1 agonist which selectively binds to EDG-1 as compared with EDG-3 at least 20 folds was effective for immune disorder (see, WO 03/061567).

Biological Example 1 Measurement of Inhibitory Activity of the Compound of the Present Invention on Binding of [³H]-PhS1P to EDG-6 Method:

By using cell membrane fraction of an EDG-6-overexpressing Chinese Hamster Ovary (CHO) cell and 1 mg protein/mL of the membrane fraction, reaction was carried out in a 96-well plate. Into each well, 80 μL of a vehicle (DMSO) solution diluted with 2× binding buffer (100 mmol/L Tris pH 7.5, 200 mM NaCl, 30 mM NaF, 1% BSA) or a ligand solution having a twice higher concentration and 40 μL of 10 nmol/L [³H]-PhS1P (5,5,6,6,-tetralithium phytosphingosine 1-phosphate: This was prepared in the following manner. A compound (anti-7-tert-butyl (4S)-4-[(1S,2R)-1-(benzyloxy)-2-hydroxyhexadec-3-yn-1-yl]-2,2-dimethyl-1,3-oxazolizine-3-carboxylate) prepared in accordance with a method reported in a document (Tetrahedron Lett., 38(34), 6027-6030 (1997)) was reacted with benzyl bromide in tetrahydrofuran in the presence of potassium hexamethyldisilylamide to thereby protect the hydroxy group of the compound. Then, it was treated in hydrogen chloride/methanol solution to remove an acetonide group. The compound thus obtained was reacted with N,N-diethyl-1,5-dihydro-2,4,3-benzodioxaphosphepin-3-amine in dichloromethane in the presence of tetrazole and then oxidized with m-chloroperbenzoic acid. Then, it was reacted in the presence of ASCA-2 catalyst (manufactured by NE Chemcat, 4.5% palladium-0.5% platinum catalyst carried on active carbon, see, Fine Chemical, Oct. 1, 2002, pages 5 to 14) in methanol under a tritium atmosphere. The obtained compound was treated with a 4 N hydrogen chloride/1,4-dioxane solution in dichloromethane to thereby obtain the desired compound) were added. Further, 40 μl of the membrane fraction solution was added and reacted at room temperature for 60 minutes. After the completion of the reaction, the reaction mixture was filtered by aspiration with a 96-well Unifilter, washed with 50 mL of a washing buffer (50 mmol/L Tris pH7.5, 0.5% BSA) thrice and dried at 60° C. for 45 minutes. Then, 50 μl/well of Micro Scint 20 was added and the plate was covered with Top Seal-P. Then the radioactivity was measured with Top Count (Perkin Elmer).

Results:

The compounds of the present invention showed inhibitory activities on the binding of [³H]-PhS1P to EDG-6. For example, IC₅₀ values of the compounds prepared in Example 27, Example 37-1, and Example 66-24 were 26, 98, and 81 nmol/L, respectively.

Biological Example 2 Counting the Number of Lymphocyte in Blood Method:

Test compounds were orally administered to male BALB/c mice or male Sprague-Dawley rats (Charles Riber Laboratories, Japan, Ltd., 6-week-old at the time of use). Four to 72 hours after the administration, the blood was collected from the aorta abdominalis under ether anesthesia. The number of the total leucocyte count, the lymphocyte count, the neutrophil count, the erythrocyte count, the platelet count in blood and the hematocrit value were measured with a multipurpose automatic blood cell counter (SF-3000, Sysmex). Evaluation was made by setting the average blood cell count in a vehicle-administered group (vehicle group) as 100% and calculating the percentage of vehicle from the average blood cell count of each test compound-administered group. Based on the test compound doses and percentages of vehicle with the doses, the dose of the compound required for lowering the blood cell count to 50% was calculated as ED₅₀.

Results:

The compounds of the present invention significantly lowered the number of lymphocyte in blood in a dose of 10 mg/kg.

Biological Example 3 Evaluation of an Agonistic Activity Against EDG of the Compound of the Present Invention by Monitoring Changes in Intracellular Calcium Ion [Ca²⁺]_(i) Concentration Method:

Human EDG-1, EDG-3, EDG-5 or EDG-8 gene overexpressing CHO cells were cultured in Ham's F12 medium (manufactured by GIBCO BRL) containing 10% FBS (fetal bovine serum), penicillin/streptomycin and blasticidin (5 μg/ml). The cultured cells were incubated in a 5 μM Fura2-AM solution (Ham's F12 medium containing 10% of FBS, 20 mM HEPES buffer (pH7.4), and 2.5 mM probenecid) at 37° C. for 60 minutes. After washing once with Hanks solution containing 20 mM HEPES buffer (pH7.4), and 2.5 mM probenecid, the plate was soaked in the same solution until assay. Then, the plate was set on a fluorescent drug screening system (FDSS 6000; Hamamatsu Photonics) and the intracellular calcium ion concentration was measured without stimulation for 30 seconds. A test compound (final concentration: 1 nM to 10 μM, dimethylsulfoxide (DMSO) solution) was added and S1P (final concentration: 100 nM) was added 5 minutes thereafter. Then, the increase in the intracellular calcium ion concentration was measured before and after the addition of S1P at intervals of 3 seconds (excitation wavelength: 340 nm and 380 nm, fluorescence wavelength: 500 nm).

The agonistic activity of the compound against each EDG was determined by using the peak value due to S1P-stimulation in a well containing DMSO as a substitute for the evaluated compound as a control value (A), comparing the value before the addition of the evaluated compound with the increased value (B) in the fluorescent ratio after the addition, and calculating the increase ratio (%) in the intracellular calcium ion [Ca²⁺]_(i) concentration as: increase ratio (%)=(B/A)×100. Increase ratios of the compound at individual concentrations were determined and the EC₅₀ was calculated.

Results:

It was indicated that the compounds of the present invention showed an agonistic activity against EDG-1. For example, EC₅₀ values of the compounds prepared in Example 5 and Example 6 were 7.8 and 0.25 μmol/L, respectively.

Biological Example 4 Mouse Model of Dermatitis Caused by Continuous Application of Hapten Method:

A 1% (w/v) 4-ethoxymethylene-2-phenyl-2-oxazolin-5-one (hereinafter, abbreviated as “oxalon”) solution was applied (20 μL) to an ear auricle (right, both faces) of mice (male Balb/c) to perform the primary sensitization. Seven days after the sensitization, a 1% (w/v) oxalon solution was applied (20 μL) for elicitation (Day 0). The same procedure as the Day 0 was repeated on the days 2, 4, 6, 8, 10, 12, 14 and 16. A test compound was dissolved in a vehicle and then orally administered or applied to both faces of the right ear (20 μL) before the application of oxalon. To the control group, only the vehicle was applied. Immediately before the administration of the test compound and 24 hours after the oxalon application, the thickness of the mouse ear auricle was measured with Dial Thickness Gauge (Ozaki Seisakusho) as an indication of the efficacy to the mouse model of dermatitis induced by the continuous application of hapten.

Biological Example 5 Adjuvant-Induced Arthritis Model Method:

Evaluation was made by using 7 weeks male or female Lewis rats. After measuring the volume of the left hinder leg of a rat, a 500 μg/rat suspension of dry Mycobacterium butyricum cells (Difco), which was employed as an adjuvant, in liquid paraffin is subcutaneously injected into the right hinder foot pad. Thus, a rat adjuvant-induced arthritis model was constructed. By comparing a test group to which a test compound had been orally administered with a control group of to which administration is not performed, the therapeutic or preventive effect was evaluated.

Biological Example 6 EDG-6 Signaling Detecting Method Based on Measurement of Phosphorylated ERK Method:

EDG-6 (S1P₄) receptor expressing CHO cells, which had been subcultured in Ham's F12 medium (manufactured by GIBCO BRL) containing 10% FCS and Geneticin (250 μg/mL) were seeded in a 6-well cell culture plate (available from Coaster) at 5×10⁵ cell/well, and incubated overnight under conditions of 37° C. and 5% CO₂. After the incubation, the medium was removed from the culture plate, Ham's F12 medium containing 0.1% BSA (Fatty acid Free) was added to the culture plate, and incubated overnight under conditions of 37° C. and 5% CO₂. The medium was removed after the incubation, and then Ham's F12 medium containing 0.1% BSA (Fatty acid Free) in which various concentrations of test materials were dissolved was added to the culture plate, and the plate was reacted for 10 minutes at room temperature. After that, the medium was removed and cells were washed with an ice-cold PBS. 100 μL of Lysis buffer (20 mmol/L Tris-HCl pH 7.5, 1% Triton X-100, 1 mmol/L EDTA, 1 mmol/L EGTA, 0.5 mmol/L Na₃VO₄, 50 mmol/L NaF, 1× Complete Protease inhibitor Cocktail) was added to each well, and the plate was reacted on ice for 5 minutes to dissolve the cells. SDS-PAGE sample buffer was added to a supernatant of the cell lysate and treated at 100° C. The resultant was used as a sample for electrophoresis and separated by means of SDS-PAGE. The separated sample was transferred to a PVDF membrane (Immuno Blot PVDF membrane, trade name, manufactured by BIO-RAD). Phosphorylated ERK on the membrane was allowed to react with anti-phosphorylated ERK (p42/44 MAPK) polyclonal antibody (Phospho-p44/42 MAP Kinase (Thr202/Tyr204) Antibody, trade name, manufactured by Cell Signaling Technology), and further react with an HRP-labeled anti-rabbit IgG antibody (manufactured by Cell Signaling Technology). After that, a band developed from the resultant by using ECL plus Reagent (manufactured by Amersham) was detected by means of Science Imaging System (LAS-100, trade name, manufactured by FUJI FILM). Comparison between a group which was added with a test material and a group which was not added with a test material enables detection of EDG-6 signaling.
